Urth Lens Mount Adapter Contax/Yashica (C/Y) Lens to Sony E Camera

No, this is a manual adapter. Autofocus is not supported. You will need to focus manually using the lens's focus ring.

Aperture control depends on the lens itself. If your Contax/Yashica (C/Y) lens has an aperture ring, you can control it manually on the lens. If the lens relies on electronic aperture control, this adapter cannot provide it.

No, this adapter does not electronically communicate with the camera. EXIF data for aperture and shutter speed will not be recorded.

Yes, it is designed to be compatible with all cameras featuring the Sony E-mount, including full-frame and APS-C sensor models.

The adapter is meticulously machined from hardened aluminum and copper for durability and a secure fit.

The adapter has an anti-reflection matte finish to minimize internal reflections. When properly seated, it provides a light-sealed connection. Image quality will primarily depend on the performance of the attached C/Y lens.

Gently wipe the mounting surfaces with a dry, lint-free cloth. Avoid using liquids or abrasive cleaners.

Ensure mounting surfaces are clean and free of debris. Realign the mounting dots and try again, applying gentle, steady pressure until it clicks into place. Check for any obstructions.

Confirm that manual focus is being used on the lens. Ensure the adapter is fully seated on the camera and the lens is fully seated on the adapter. Adjust focus carefully using the lens's focus ring and your camera's live view or focus peaking feature.

The adapter should provide a light seal. If leaks are present, inspect the mounting surfaces of the lens, adapter, and camera for damage or debris. Ensure the adapter and lens are securely locked in place.

Set your camera to manual exposure mode (`M`). The adapter does not support electronic communication, so automatic metering will not function. Adjust aperture on the lens (if possible) and shutter speed on the camera manually.
